Communications over the world wide doesnt depend on sytax or eloquence or rethoric or articulation but on the emotional context in which the message is being heard.
People can only hear you when they are moving toward you and they are not likely to when your wordss are pursuing them
Even the choices words lose their powe when they are used to overpower.
Attitudes are the real figures of speech '-Friedman

Biometrics, the future in electronic commerce


 Biometrics refers to authentication techniques that rely on measurable physical characteristics that can be automatically checked.
There are several types of biometric identification schemes:
Though the field is still in its infancy, many people believe that biometrics will play a critical role in future computers, and especially in electronic commerce. Personal computers of the future might include a fingerprint scanner where you could place your index finger. The computer would analyze your fingerprint to determine who you are and, based on your identity, authorize you different levels of access. Access levels could include the ability to use credit card information to make electronic purchases.
 The aspect of a biometric security system that administers the biometric data during the enrollmentcaptureextractioncomparison and matchingstages of the process. The biometric engine is a software program that works in conjunction with the hardware devices that a biometric system uses. 
NEC is a biometrics pioneer holding a leadership position in biometrics matching technology since the 1970's. 
Today, with more than 200 deployments in over 30 countries, NEC continues to be the leading provider and one of the largest market share holders of Automated Biometrics Identification Systems (ABIS) worldwide.

With its commitment to research and development (R&D), NEC continues to provide the most innovative and accurate algorithms that meet and exceed the highest standards set by the National Institute of Standards and Technology (NIST). Working with NEC means accessing decades of biometrics expertise and technologies for optimal performance, accuracy and reliability.
Biometrics refers to the automatic identification of a person
 based on his /her physiological or behavioral characteristics. 
This method of identification is preferred over traditional
 methods involving  passwords and PIN numbers
 for various reasons:

• The person to be identified is required to be 

physically present at the point-of-identification;
• Identification based on biometric techniques 

obviates the need to remember
 a password or carry a token.

• Complete system installation
• Network and software installation
• Proximity Credential Readers
• Biometric-Hand geometry and Retinal Scan
• Anti-pass Back Optical Turnstiles
• Long-Range Hands-free Technology
• Integrated Video I.D. Badging
• Networked Multiple Site Integration
• Auditing and reporting configuration

Cloud Computing,Implementation and Key Considerations

 

Cloud computing is a significant evolution. It’s changing the way we think about how we deliver our computational infrastructure to end users. Determining which strategy is right for your organization depends on your key business goals, requirements, and IT capabilities. This webinar discusses key considerations that enterprise and government organizations need to take today to assess readiness for cloud computing, including: • Identifying the business drivers behind cloud computing initiatives. • Understanding your organizational readiness for cloud computing. • Establishing an open standards-based infrastructure. • Developing a comprehensive roadmap for making cloud a reality for your enterprise: o Building the business and technical case for cloud. o Developing a strategy around open source standards, products, and tools that aligns with your business goals. o Assessing organizational and infrastructure readiness. o Deploying a prototype cloud infrastructure. o Developing an actionable roadmap for enterprise implementation. The advent of the cloud for servicing individual users opens a whole new level of opportunity. Every user can now have a scalable and nearly infinite set of resources available for whatever they need to do. The impacts for IT infrastructures are stunning, but when this is applied to the individual, there are some specific benefits that emerge. Users’ digital activities are far more self-directed than ever before. Users demand to make their own choices about applications, services and content, selecting from a nearly limitless collection on the Internet. This encourages a culture of self-service that users expect in all aspects of their digital experience. Users can now store their virtual workspace or digital personality online. Virtualization has improved flexibility and increased the options for how IT organizations can implement client environments. Virtualization has, to some extent, freed applications from the peculiarities of individual devices, operating systems or even processor architectures. Virtualization provides a way to move the legacy of applications and processes developed in the PC era forward into the new emerging world. This provides low-power devices access to much-greater processing power, thus expanding their utility and increasing the reach of processor-intensive applications.

Nanotechnology /Nanoscience

 


We define nanoscience as the study of phenomena and manipulation of materials at atomic, molecular and macromolecular scales, where properties differ significantly from those at a larger scale; and nanotechnologies as the design, characterisation, production and application of structures, devices and systems by controlling shape and size at the nanometer scale. In some senses, nanoscience and nanotechnologies are not new. Chemists have been making polymers, which are large molecules made up of nanoscale subunits, for many decades and nanotechnologies have been used to create the tiny features on computer chips for the past 20 years. However, advances in the tools that now allow atoms and molecules to be examined and probed with great precision have enabled the expansion and development of nanoscience and nanotechnologies.



The properties of materials can be different at the nanoscale for two main reasons:
First, nanomaterials have a relatively larger surface area when compared to the same mass of material produced in a larger form. This can make materials more chemically reactive (in some cases materials that are inert in their larger form are reactive when produced in their nanoscale form), and affect their strength or electrical properties.
Second, quantum effects can begin to dominate the behaviour of matter at the nanoscale - particularly at the lower end - affecting the optical, electrical and magnetic behaviour of materials. Materials can be produced that are nanoscale in one dimension (for example, very thin surface coatings), in two dimensions (for example, nanowires and nanotubes) or in all three dimensions (for example, nanoparticles).

What qualifies as "nanotechnology" today is basic research and development that is happening in laboratories all over the world. "Nanotechnology" products that are on the market today are mostly gradually improved products (using evolutionary nanotechnology) where some form of nanotechnology enabled material (such as carbon nanotubes, nanocomposite structures or nanoparticles of a particular substance) or nanotechnology process (e.g. nanopatterning or quantum dots for medical imaging) is used in the manufacturing process. In their ongoing quest to improve existing products by creating smaller components and better performance materials, all at a lower cost, the number of companies that will manufacture "nanoproducts" (by this definition) will grow very fast and soon make up the majority of all companies across many industries. Evolutionary nanotechnology should therefore be viewed as a process that gradually will affect most companies and industries.


So what exactly is nanotechnology? One of the problems facing nanotechnology is the confusion about its definition. Most definitions revolve around the study and control of phenomena and materials at length scales below 100 nm and quite often they make a comparison with a human hair, which is about 80,000 nm wide. Some definitions include a reference to molecular systems and devices and nanotechnology 'purists' argue that any definition of nanotechnology needs to include a reference to "functional systems"


The design, characterization, production, and application of structures, devices, and systems by controlled manipulation of size and shape at the nanometer scale (atomic, molecular, and macromolecular scale) that produces structures, devices, and systems with at least one novel/superior characteristic or property.
